FURNCE FOR THE DESTRUCTlON OF TOWN REFUSE.

SPECIFICATION forming part of Letters Patent No. 716,601, dated. December 23, 1902.

Application filed April 15,1902.

To LZZ whom t may concern:

Be it known that l, GEORGE WATSON, a subject of the King of Great Britain, and a resident of No. 5 Greek street, Leeds, in the county of York, England, have invented a certain new and useful Improvement Relating to Furnaces for the Destruction of Town Refuse, of which the following is a specification.

According to the present invention the cover or lid of the chargingopening of the furnace is provided with a liquid seal, whereby the escape of smoke and fumes from the furnace to the surrounding atmosphere can be prevented.

The invention consists in a certain combination which includes such cover and seal as elements and are hereinafter described with reference to the accompanying drawings, and the novelty of which is pointed out in the claim which follows.

In the accompanying drawings, Figure 1 shows in longitudinal vertical section the charging-opening of the furnace of a refusedestructor with the lid or door closed down upon its seat. Fig. 2 is a transverse section of the same. Fig. 3 is asection similar to Fig. 1, but showing the door removed and the opening ready to receive a charge of refuse. Fig. 4 is a sectionv similar to Fig. 2 with the door removed and showing means for raising and lowering covering-flaps.

6 is the charging-opening, which is placed vertically and is provided with a metal frame extending around the charging-opening, in which is formed a gutter or trough 1 to contain liquid to a depth which will provide a seal of, say, three inches of liquid.

2 is the door or lid, which is formed with a lange all around, as shown in Figs. 1 and 2, to dip into the trough l.

Vhen itis required to charge the furnace, the door is lifted from its seat and removed in a horizontal direction clear of the charging-opening. To this end longitudinal rails 4 are arranged on each side of the chargingopening to form ways for a trolley 21, provided with running wheels 3. On the top of the trolley are secured bearings for a pair of axles l1 12, carrying chain-pulleys 9 10. A pair of chains 7 are secured at one end to eyes on the door or lid 2 and passing up to and over the guide-pulleys 9 on the axle l1 are secured at their other ends to the pulleys on the axle 12. A similar pair of chains 8, also secured to eyes on the door 2, pass up to and are Serial No. 102,976. (No model.)

secured tothe pulleys 10 on the axle 12. To the outer end of this axle 12 is keyed a worm- Wheel 13, into which gears the worm 14 on theaxlel. Onrotarymotionbeingimparted to this axle by the hand-Wheel 16 the door 2 will, by means of the chains 7 8, be raised clear of the trough l, leaving the trolley, with the suspended door, free to be moved along the rails t clear of the charging-opening. This movement of the trolley is eected through the spur-wheel 18, keyed to the axle of one pair of running wheels 3, gearing with the pinion 19, keyed to an axle carried by the trolley. A handle 2O on the squared end of this axle serves to impart rotary motion to the running Wheels and the consequent removal of the door 2 from over the charging' opening.

To prevent particles of refuse or rubbish from falling into the trough 1 during the process of charging, hinged flaps 22 24 25, covering three sides of the trough, are employed, the fourth side of the trough being covered by the flap 23, carried by the tail part of the trolley, as shown at Fig. 3. The flaps 22 24 25 are raised or lowered by the chains 26 27 31, which are secured at one end to the flaps, and after passing over guide-pulleys 28 29 pass down to a balance-weight 30, and it is by the raising or lowering of this weight that the raising or lowering of the iiaps is effected.

The charging-opening 6 is preferably made rather larger at the bottom than at the top in order that the refuse may not choke in the opening.

It will be understood that the refuse may be fed into the charging-opening either by being shot directly from tipping carts or wagons or from grabs or containers.

What I claim as my invention is The combination of means for closing the charging-opening of a. refuse-destructor furnace, comprising a removable' cover and means for removing the same, a liquid seal cooperating with the cover, and means for covering the seal-trough when the cover is removed, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

G. WATSON.
